Abstract: 1193.40 US TH/AB  1977-12-05 ABSTRACT OF THE DISCLOSURE       The present invention relates to a sealing arrangement between parts, which are provided to rotate relative to each other.  The one part is provided with at least one groove, which partly encloses an O-ring of resilient material and in unaffected condition of O-shape and with a substantially circular cross-section.  The other part shows a surface provided to be pressed against the O-ring, so that the O-ring will be deformed and obtains a sealing fit against por-tions of the groove and said surface.  According to the invention the groove has a cross-section which is narrower than the cross-sec-tion of the by the pressure deformed O-ring, so that the O-ring is pressed against at least the main portion of the walls of the groove and thereby is locked in a fixed position relative to the groove.

Abstract: Case 23 - Chea SIGNAL CODING FOR COMPRESSED PULSE CODE           MODULATION SYSTEM                 Abstract A codec including an encoder section for encoding analog signals in compressed PCM (CPCM) and a decoder sec-tion for decoding CPCM information into analog signals fea-tures a single companding generator shared by the encoder and decoder sections.  In the encoder section, an analog signal to be encoded is sampled periodically and the analog samples are compared with the decaying voltage of the com-panding generator which includes a capacitor, which is in-itially charge to a fixed voltage E.  The capacitor is then discharge through a fixed resistance to another fixed vol-tage -dE, the discharge time being measured by a binary digital encoder counter from the start of the discharge un-til the voltage on the capacitor equals the absolute value of the given analog signal sample, at which time the count of the binary counter represents the desired compressed pulse code of the analog signal samples magnitude.  Addition-ally, a sign bit, derived from the analog signal sample, indicates the polarity of said sample.  In the decoder section, a CPCM input signal to be decoded is loaded into a decoder counter, which is decremented to a zero count, while the decaying voltage of the companding generator is sampled.          The resultant sample represents the magnitude of the analog signal output for the decoded CPCM code, either directly or inverted, depending upon the sign bit.          This sampled signal is further presented to a low-pass filter at a predetermined interval of the codec operating cycle dictated by the sampling frequency.  The output of low-pass filter is the desired reconstructed analog signal.

Sn3[Fe(CN)6]2 or of tin(II)-sulfide or tin(II)-telluride are mixed together in an amount, which - in respect of the reduction of the pertechnetate ions with lower valency - represents an excess, the mixing being carried out in such a way that the pertechnetate (b) or the suspension (c) is added last, the two-phase system obtained is kept in suspension and, after completion of the reduction of the pertechnetate, the solid phase is separated from the solution containing the chemical substance labelled with technetium-99m. This method had the advantage that a minimal amount of insoluble tin-containing material is carried over into the labelled solution.

Abstract: ABSTRACT          The present invention is directed to a fiber optic cable connector assembly and more particularly to fiber optic cable connectors which, when mated, form an assembly which accurately aligns and spaces the term-inal ends of one or more fiber optic pairs.  Fiber optic connector assemblies must properly align and closely space the terminal ends of the optical fiber pairs to very exact tolerances.  Fiber optic connectors have generally included terminating pins constructed from rigid material which receive the optic fibers and support them in the connector.  In many cases, damage to the pins or other connector components result during ser-vicing.  The connector assembly of the present inven-tion includes a connector having a cable terminating tubular pin which receives one of the cables and which also has an outer circumferential flange.  The pin is received within a channel of the connector body which channel has a forwardly facing annular shoulder portion. A cylindrical retainer coaxially disposed about the pin has a rear surface engaging the channel shoulder and forwardly depending fingers engaging the pin flange. The rearward end of the retainer also includes an in-tegral spring mechanism which urges the pin in the for-ward direction so that its forward end continuously engages a spacer within a mating connector which causes the terminal ends of the coupled cables to be closely and controllably spaced for efficient light transfer between the fiber optic cables.  This assembly allows ease of manufacture and facllitates disassembly of the connectors during servicing.

The method comprises the steps of directing a beam of spatially coherent, monochromatic radiation at the fiber, to thereby to generate a complex scattering pattern.  At least a portion of the pattern includes contributions from the diffraction, the reflection and the refraction of the beam by the fiber.          The scattering pattern is spatially radially disposed about the fiber and has a fringe modulation imposed thereon. The smallest angles,.THETA.1 and .THETA.2 are measured at which the modulation first appears in the fringe pattern, .THETA.1 < 0 < .THETA.2.  The deviation from concentricity is determined by comparing .THETA.1 and .THETA.2 with corresponding angles priorly measured for similar clad fibers Or known diameter and concentricity and known core and cladding refractive indices.

A switch-ing regulator is provided which is connected to the level detector and the switching transistor for modulating the actuating signal when the voltage to the rectifier input rises above a predetermined value.  The switching transistor is thus rendered periodically non-conducting to regulate the average voltage appearing across the holding coil.

The inside diameter of the holder is intermediate that of the cutting ri-g and the core barrel.  An adjustment means determines the axial spacing between. the cutting edge of the core barrel cutting ring and the lower edge of the drill bit or teeth.
